HINGE.

To all whom, it may concern:

Be it known that I, OSCAR W. MoALPIN,

a citizen of the United States, residing at Roseville, in the county of Placer and State of California, have invented certain new and useful Improvements in Hinges; and I do' declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the artto which it appertains to make and use the same.

This invention relates to improvements in hinges and more particularly to three-leaf hinges for doors and the like.

The object of the invention is to provide a simply constructed and eflicient hinge of this character which is adjustable to vary the position of the door relative to the casing or the jamb to whichever it is applied and which is equipped with a lever for securing it in adjusted position.

With this and other objects in view, the

invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a front elevation of a portion of a door and its casing showing this improved hinge applied. Fig. 2 is a horizontal section through the door and its casing showing a plan View of the hinge. Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1. Fig. 4 is a front elevation of this improved hinge detached and with the parts thereof disassembled and arranged in juxtaposition ready for assembling. Fig. 5 is a transverse section taken on the line 5-5 of Fig. 2.

In the embodiment illustrated, a hinge is shown composed of a leaf 1 designed for attachment to either a casing or jamb of a door as may be desired and which is provided with the usual knuckles 2 adjacent its upper and lower ends and with the usual apertures 3 for the passage of the fastening elements. Another leaf 4 is shown for attachment to the door D and this leaf is provided with the usual apertures 5 vfor'the passage of the fastening elements and with knuckles 6 for the reception of a pintle 7.

An intermediate leaf 8 is designed to connect the leaves 1 and 4 and is shown provided on each edge with a pair of knuckles 9 and 10 respectively which are adapted to be disposed in alinement with the knuckles of the leaves 1 and 4, the knuckles 9 being Specification of Letters Patent.

shown at 12 to Patented. May 25, 1915.

Application filed March 4, 1915. Serial No. 12,124.

adapted to cooperate with the knuckles 2 of the leaf 1 and the knuckles 10 with the knuckles 6 of the leaf 4 and which are connected' thereto by the usual pintles.

A lever 11 is mounted on the pintle which connects leaves 1 and 8 and is here shown disposed midway the width of said leaves and is here shown in the form of a compound curve U-shaped in cross section as 7 provide additional strength. The free end of this lever- 11 is longitudinally slotted as shown at 13 and surrounding said slot on the inner face thereof are a plurality of serrations 14 which are designed to engage the outer face of the leaf 4 to assist in holding said lever and leaf in adjusted position relatively to each other. A screw 15 extends through the slot 13 of the lever 11 and through leaf 4 into the door and is designed for securely connecting said lever and leaf in adjusted position. By loosening the screw 15, the lever 11 may be adjusted three-eighths of an inch either to the right or the left of the center as may be desired.

This hinge is applicable to any kind of door large or small and may be constructed of any suitable material, leaf 1 being designed to be set either on the jamb of the door the same as other hinges or on the casing but is preferably mounted on the casing, and by setting the casing three eighths of an inch past the j amb forms a groove between the stop and casing for the rear edge of the door.

I claim as my invention:

1. A hinge comprising leaves for attachment to a door and easing respectively, an intermediate leaf connecting the inner ends of said first-mentioned leaves, and a lever mounted on the connecting pintle of one of said first-mentioned leaves, and means for connecting said lever with the other leaf.

2. A hinge comprising leaves for attachment to a door and easing respectively, an intermediate leaf connecting the inner ends of said first-mentioned leaves, a lever mounted on the connecting pintle of one of said first-mentioned leaves, and means for adjustably connecting the other end of said lever with the other leaf.

3. A door hinge comprising two leaves having knuckles at their inner ends, another leaf disposed between the knuckled ends of said leaves and pivotally connected therewith, a lever pivoted at one end to the knuckled end of one of said leaves and having a longitudinally extending slot in its free end, and a fastening element extending through said slot and engaging the other leaf whereby said lever and leaf are adjustably connected. o

4:. A hinge comprising a pair of leaves having knuckles at their inner ends; an intermediate leaf pivotally connected With the knu'ckled ends of said leaves, and a lever in the form of a compound curve having one end pivotally connected With the inner knuckle of one of said first-mentioned leaves, and its other end adjustably connected With the other of said first-mentioned leaves.

5. A hinge comprising'a pair of leaves having knuckles at their inner ends, an intermediate leaf pivotally connected With the knuckled ends of said leaves and a lever in the form of a compound curve having one end pivotally connected With the inner knuckled end of one of said first-mentioned leaves, and its other end longitudinally slotted and provided on its inner face around- Witnesses: V
